So not adequate to meet such, conditions. v much.of the tilting structure just described is Accordingly, it is theobject of this invention standard and operates in the usual way; that 20to provide an adidtional tilt control mechanism is, when the lever 23 ismoved'ahead, the eye K 35 having a transverse axle lficarried in a pairof matically a sufiicient amount to prevent their extending cutter bar20 shown in section, to which a set-collar 3'7 anchored in any desiredposition 5'5-0 bar 20 may be vertically adjusted, the connections abruptrise of the ground makes it necessary to for a mowingmachine, so thatthe cutter bar 28 engages the stop nut 30 topull the rod 29 'may easilybe caused to ride over raised ground back, thereby tilting the yoke 17and cutter bar formations which cannot now be adequately taken 20therewith, rearwardly about axis 18 through care of by present knownforms of tilting mechalever 31.

By crumedat 33 on the main frame with a lower means of coupling elements 15 and16, a yoke 17 is end 34 extending downwardly beyond the fulpivotallycarried on pivot 18 to permit the yoke 17 crum 33. The part 34 of thelever has connected 7 to pivot up or down about a transverse horizontalto it a flexible connection in .the form of a cable axis in a mannerwell known in this art. Asso- 35 that is trained around a pulley wheel36, which ciated with the yoke 17 is the inner shoe 19. The may becarried by the lower end of lever 23, said yoke also carries in theusual way the transversely cable 25 then passing forwardly to be securedto the guard fingers 21 are connected in the usual on the rod 29.Obviously, actuation of the foot manner. The cutter bar structure 2021with lever 32 will cause the cable 35, through the the shoe 19 ishingedly connected at 22 to the structure described, to pull the rod 29rearwardly yoke 17 in the usual manner, so that the cutter to tilt theyoke 17 and cutter bar 20 when an for so adjusting the mower bar notbeing shown, quickly tilt the cutter bar. as this is standard in the artand not a part It will be seen that the-foot lever 32 is conof thisinvention; the present invention, relating veniently accessible to theoperator from his seat only to the means for tilting the yoke 17 about24 and that he can actuate the same at any time the axis 18, so that theguard fingers 21 may be upon approaching a levee ridge or the like,with- 7-110 out bothering to actuate the lever 23 which may remainlocked to maintain the normal set or tilt position of the cutter bar.

The two levers 23 and 32 are selectively operable independently of eachother as the operator may desire.

From this detailed description it will be seen that an improved tiltmechanism has been provided for mowers, which achieves the desirableobject heretofore recited. It is the intention to cover all such changesand modifications of the example of the invention herein shown as do notdepart from the spirit and scope of the invention which is set forth inthe following claims.

What is claimed is:

1. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, a hand lever on the main frame connected totilt said bar, and a foot lever connected to tilt the bar, said leversbeing selectively operable.

2. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, a hand lever on the main frame connected totilt said bar, and a foot lever connected to tilt the bar independentlyof the hand lever.

3. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, a hand lever on the main frame connected totilt said bar, a foot lever fulcrumed on the frame, and flexibleconnections between said'foot lever and bar to tilt the latter.

4. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, a foot lever carried on the frame, andflexible connections between said lever and bar to tilt the latter.

5. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, a hand lever carried by the frame, a rodslidably connected with the hand lever to tilt the bar, said slidableconnection adapting the bar for automatic tilting movement as the barrides over uneven ground, and foot lever controlled means for positivelytilting the bar, said foot lever having connection with the rod.

6. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, a hand lever carried by the frame, a rodslidably connected with the hand lever to tilt the bar, said slidableconnection adapting the bar for automatic tilting movement as the barrides over uneven ground, a foot lever carried on the frame, andflexible connections between the foot lever and rod positively to tiltthe bar.

7. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, a hand lever carried by the frame, a rodslidably connected with the lever below 'its fulcrum, said rod connectedto'tilt the bar, a second lever carried on the frame, and connectionsbetween said second lever and rod positively to tilt the bar uponactuation of the second lever.

8. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, a hand lever carried by the frame, a rodslidably connected with the lever below its fulcrum, said rod connectedto tilt the bar, a foot lever carried on the frame, a set-collaranchored on'the rod, a pulley, and a flexible connection from the footlever passed around the pulley and secured to said set-collar.

9. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, and a plurality of selectively operablelevers on the frame connected to tilt said bar.

10. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, a hand lever on the main frame connected totilt said bar, and a second lever to tilt the bar independently of thefirst lever.

11. In combination, a mower having a main frame, a cutter bar tiltablyconnected to the main frame, a first lever for tilting the bar, a second18- ver, and flexible connections between the second lever and bar totilt the bar independently of the first lever. r

12. In combination, a mower having a frame, a cutter bar tiltablyconnected to the frame, means .including a lever and detent mechanismfor controlling the'tilt of said bar, said detent mechanism serving tolock the lever and hold the bar in a predetermined tilted position, andadditional means to augment the tilt of the cutter bar.

13. In combination, a mower having a frame, a cutter bar tiltablyconnected to the frame, means including a hand operated 'lever' anddetent mechanism for controlling the tilt of said bar, said detentmechanism serving to lock the lever and hold the bar in a predeterminedtilted
